This was tested in people. That is the most reliable kind of research we share.
This looked back at records of real patients. It is not a new treatment.
The short version
People had fewer problems after this surgery at hospitals that do it often.
What was studied. Researchers looked at U.S. hospital records from 2013 to 2022. The records covered an estimated 19,883 adults who had surgery for a hearing nerve tumor called vestibular schwannoma.
What they found. Of those patients, 13,007 (65%) had their surgery at a high volume hospital. A high volume hospital was one that did at least 10 of these surgeries a year. Patients treated there were less likely to have serious problems, face drooping, trouble swallowing, or stroke type events. Their hospital stays were shorter, and fewer of them were sent somewhere other than home.
What this means, and what it doesn't
What it could mean: Where you have this surgery may matter. You can ask a surgeon how many of these operations their hospital does each year. The authors think care for these tumors may work better at centers that do a lot of them.
What it doesn't mean: This does not prove that busy hospitals cause the better results. The team looked back at past hospital records. It was not a trial that put people into groups. Patients at the busy hospitals were younger and had higher incomes, so some of the gap may come from that. This is not a new treatment and not a cure. Your own risk depends on your tumor, your health, and your care team.
